IMPROVEMENT lN SHUTTER-WORKERS.

Specification forming part of Letters Patent No. 138,879, dated May 13,1873; application filed February 12, 1873.

To all whom it may concern:

Be it known that I, AUGUSTUS H. Games, of Norwalk, in the county ofFairfield and State of Connecticut, have invented a new and ImprovedDevice for Operating Window- Shntters; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, which willenable those skilled. in the art to make and use the same,reference'being had to the accompanying drawing forming part of thisspecification, in which drawing- Figure 1 represents a horizontalsection of this invention. Fig. 2 is a transverse vertical section ofthe same.

Similar letters indicate corresponding parts.

This invention consists in combining with a v'indow-shutter a bell-cranklever, which has its fulcrum on a pivot secured in the windowsilloutside of the window, and one arm of which connects by a link with abracket secured to the shutter, while its other arm connects with abutton that slides in a segmental slot in the window-sill inside of thewindow, in such a manner that, by moving the button in its segmentalguide-slot, the shutter can be opened or closed without opening thewindow. The button is so arranged that it can be secured in any part ofits guide-slot so as to retain the shutter in any position into which itmay be brought.

In the drawing, the letter A designates a shutter, which swings onhinges a in the usual manner. Close to the lower hinge is a bracket, 1),secured to the shutter, and this bracket connects, by a curved link, c,with one arm, (I, of the bell-crank lever (Z c. This bellcrank lever hasits fulcrum on a pivot, f, secured in the window-sill outside of thewindow, and its arm 0 connects with a button, g, which slides in asegmental guide-slot, h, in the windowsill inside of the window. Bymoving this button in its guide-slot the shutter is opened or closed.The button 9 is screwed into the arm 0 of the bell-crank lever, and itis provided with a flange which bears on the surface of the guide-plateh, so that by screwin g up said button the arm c is drawn up tightagainst the inner surface of the guide-plate, and the shutter isretained in the position which it may occupy.

When the shutter is constructed in two halves, as shown in the drawing,each shutter is provided with its distinct device for open ing, closing,or fastening the same; and I am enabled to secure the shutters in theirclosed position or in their open position, or in any intermediateposition in which the same may be brought; furthermore, the shutter canbe operated without raising the windows, and the ordinary devices forretaining the shutters when the same are open or closed can be dispensedwith.

My device has also the great advantage that it does not produce anyobjectionable projection on the interior of the window-frame, and, ifproperly constructed, it will form an ornament for the window.

I do not claim a chain, made up of a series of links, Working in a guideand operated upon by a thumb-screw for opening and closing a shutter;neither do I claim, broadly, operating a shutter from the inside of thewindowsash by means of the two pivoted curved 1evers, for such devicesare old and well known, and require much strength to operate them,besides, the operating-lever projects on the interior beyond the sill,and while the 1necl1- anisrn upon the shutter and its lever are exposedon the outside, thus disfiguring the finish of the shutters.

What I claim as new, and desire to secure by Letters Patent, is

1. The bell-crank lever d c pivoted at f on the outside sill, one arm ofwhich is pivoted to the curved link 0 of the bracket b, while its otherarm connects with the adjustable button g, moving in the guide-plate h,secured to the sill inside of the Window, the whole combined andarranged, substantially as described, for operating a windowshutter orblind, as set forth.

2. The bell-crank leverd e pivoted at f on the outside sill, incombination with the curved link 0, said link being pivoted to thebracket and to the lever, as shown, for operating in connection with thebutton g moving in the guide-plate h arranged on the sill inside of thewindow, the several parts being constructed, substantially as described,for opening and closing a window-blind, as set forth.
